php - Joomla : how to get the url of a specific Menu itemID?

Question

Friends a newbie question.........I need help in getting the URL of a specific Menu itemID. The situation is like this:

I am running Joomla and asking for a user to input for a menu ID and choose a layout for that menu ID.

I want to do something else with this URL of the Menu itemID.

How can I get the URL of this Menu itemID provided by the user?

For Example if the user input is liek $this->get ('menulayoutid'>; and he inputs and ID of 54 then how do I get the URL for Menu ID 54.

Please note: I want to get this URL from within my PHP file and not in the browser so that I can use the value of that URL for some other purpose.

Kindly help.

$itemid = JRequest::getVar('Itemid');
$application = JFactory::getApplication();
$menu = $application->getMenu();
$item = $menu->getItem($itemid);
$link = new JURI($item->link);
$link->setVar('ItemId', $itemid);
